Adverts will soon appear at the top of the AI tool ChatGPT for some users, the company OpenAI has announced.
The trial will initially take place in the US, and will affect some ChatGPT users on the free service and a new subscription tier, called ChatGPT Go.
This cheaper option will be available for all users worldwide, and will cost $8 a month, or the equivalent pricing in other currencies.
OpenAI says during the trial, relevant ads will appear after a prompt - for example, asking ChatGPT for places to visit in Mexico could result in holiday ads appearing.
